Power for your speakers

Kicker's CX300.4 4-channel amplifier delivers 40 watts RMS to each of your front and rear speakers, or you can drive a couple of subs with up to 150 watts RMS each in 2-channel mode. And they don't cut any corners building this amp, using oversized transistors, special transformers, and a heavy-duty heat sink to bring you reliable power that won't fade when you push your system hard. Built-in high- and low-pass filters help you sculpt the sound to get the most out of your system, while variable bass boosts allow you to add some low-end punch to your front and rear channels separately.

Kicker includes hardware for vertical mounting.

Hooks in almost anywhere in almost any position

Kicker uses their Fail-Safe Integration Technology (FIT™) to keep this amp's input free from noise or interference, so you'll get a clean signal from almost any system, even a factory radio. Rugged metal end panels provide even more shielding from radiated interference. The CX300.4 also comes with hardware that lets you you mount it vertically, so you can put it in a location that takes up very little floor space and looks ultra-cool.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Features

CEA 2006 Compliant: The Kicker CX300.4's power ratings are
measured under conditions approved by the Consumer Electronics
Association (CEA). These standards allow you to accurately compare the rated
power output of all CEA 2006-compliant amplifiers, even from different brands.
Manufacturers who adhere to the standards can display the CEA 2006 logo on their
products and packaging.

Kicker Livin' Loud Certified Power: The amplifier comes with
a certificate that indicates the total maximum wattage of the particular
amplifier, along with the model number, serial number, and whether the amplifier
passed the total harmonic distortion, signal-to-noise ratio, and protection
circuit tests.

Auto Turn-on: The amp offers two automatic turn-on modes:

+12V: connect a wire from the remote
turn-on lead from your source unit to the REM terminal on
the amplifier; this is the preferred turn-on method

DC Offset: turns the amp on when a
6-volt DC offset is detected at the high-level speaker
inputs when the source unit is turned on

Vertical Mounting: The amp can be mounted vertically using
the included brackets. The vertical dimensions are approximately:

Width: 13-1/4"

Height: 7-1/4"

Depth: 2-3/8"

Signal to Noise Ratio: The S/N under CEA-2006 compliant
conditions (1 watt output) is 75 dBA. The S/N at rated power is 95 dB.

Controls

Input Level Switch: Set the input level switch to Lo when
using preamp level input signals and Hi when using speaker level input signals.

Fader: When your source unit has discrete front and rear
outputs, set the fader switch to on. Turn the fader switch off to send a single
stereo input to both the front and rear amps.

Gain: The front and rear sections of the amplifier (Amp1
and Amp2) have independent rotary gain controls, continuously variable from
125 mV to 5 V when the Input Level switch is set to Low and 250 mV to 10 V
when the Input Level switch is set to High.

Crossover: The front and rear sections of the amplifier also
have independent crossover circuits:

Mode: three position switch; Off (crossover bypassed),
Hi (high-pass), an Lo (low-pass)

Frequency: continuously
variable from 50 to 200 Hz; the slope is 12 dB per octave

Bass Boost: The bass boost circuit is continuously variable
from 0 to +12 dB and centered at 40 Hz. The front and rear amps have separate bass
boost controls.

Speaker Outputs: terminal strip with four
pair of outputs; accepts spade connectors up to 0.325" wide

Note: The Amplifier is not equipped with an internal fuse.
An external 60-amp fuse (not included) must be installed on the power wire.
If the system has only this amp and a wiring kit is used that includes a
fuse with a value other than 60-amps, the original should be replaced with
a 60-amp fuse.

Right Side of Amplifier:

RCA Inputs: two pair of stereo
RCA inputs (Amp1 and Amp2); also used for speaker
level input (up to two of item number
206KiSL needed, sold separately)

Amp Wiring Kit: Kicker recommends using an 8-gauge wiring kit
with this amplifier.
